FIG. 3 is a flow chart for explaining the music file reproducing processof the mobile communication terminal according to an exemplaryembodiment of the present invention.

Referring to FIGS. 1 to 3, the control unit 160 converts the signalreception sound output mode of the mobile communication terminal 100 tothe manner mode on the basis of the user's request and performs thecorresponding operation at step S110.

The control unit 160 examines whether the reproduction of music files,for example, MP3 files, is requested by a user during the manner mode ofthe mobile communication terminal 100 at step S120.

If the reproduction of the music files are requested by the user, thecontrol unit 160 starts the music file reproduction mode, for example,MP3 reproduction mode, of the mobile communication terminal 100 andoutputs a confirmation message for determining whether the music filesare to be reproduced or not during the manner mode at step S130. Theconfirmation message informs the user that the mobile communicationterminal 100 is performing the manner mode when the reproduction of themusic files is requested by the user, and enables the user to confirmwhether the music files are to be reproduced or not during the mannermode of the mobile communication terminal 100. The confirmation messageis output in a voice message through the audio processing unit 130 or ina letter message through the display unit 190.

The control unit 160 determines whether the external output device isconnected to the mobile communication terminal 100 at step S140. Theexternal output device may comprise an earphone or a speaker and themobile communication terminal 100 can be connected to the externaloutput device through a wireless or a wired manner. Referring to FIG. 1,the control unit 160 determines whether the earphone 200, that is, theearphone jack 220 is inserted into the jack connecting unit 145.

The control unit 160 determines that the output confirmation message isconfirmed by the user if the external output device is connected to themobile communication terminal 100 (that is, if the earphone jack 220 isinserted into the jack connecting unit 145) at step S150. Then, thecontrol unit 160 reproduces the music files selected by the user at stepS160. The audio signals of the reproduced music files are output throughthe external output device. Meanwhile, the control unit 160 can controlthe mobile communication terminal 100 such that the mobile communicationterminal 100 may reproduce the music file only when the user requests itin a state in which the external output device is connected to themobile communication terminal 100.

The control unit 160 determines whether the external output device isdisconnected from the mobile communication terminal 100 during thereproduction of the music files at step S170. For instance, if theearphone is connected to the mobile communication terminal 100, thecontrol unit 160 determines whether the earphone jack 220 isdisconnected from the mobile communication terminal 100.

If the external output device is disconnected from the mobilecommunication terminal 100, the control unit 160 outputs a message forinquiring the user whether reproduction of the music files must becontinued at step S180.

Then, the control unit 160 determines whether a confirmation key isinput at step 190. If the confirmation key is input, the control unit160 determines that the user wants to end the reproduction of the musicfiles, so the control unit 160 ends the reproduction of the music filesat step 195.

On the other hand, if incoming call signals are received during thereproduction of the music files, it is preferable that the control unit160 stops the reproduction of the music files and outputs an indicationof the reception of the incoming call signals by vibration or withoutsound according to the set manner mode.

It should be noted that although an exemplary embodiment of the presentinvention exemplifies the case in which an earphone jack 220 isconnected to the mobile communication terminal 100, the process of FIG.3 can be applied to the case in which a jack of an exterior speaker isconnected to the mobile communication terminal 100 in a wireless manner.

FIGS. 4A and 4B are exemplary views for explaining the operation of themobile communication terminal according to an exemplary embodiment ofthe present invention.

FIG. 4A shows the mobile communication terminal 100 and the earphone 200to explain the operation of the mobile communication terminal 100according to an exemplary embodiment of the present invention.

Referring to FIG. 4A, the earphone jack 220 is not inserted into thejack connecting unit 145 of the mobile communication terminal 100, andthe confirmation message for determining whether the music files are tobe reproduced or not in response to the request for the reproduction ofthe music files during the manner mode is being output on the screen.

In the state of FIG. 4A, if the earphone jack 220 is inserted into thejack connecting unit 145 by the user, the mobile communication terminal100 determines that the output confirmation message is confirmed by theuser and outputs the music files selected by the user through theearphone 200 as shown in FIG. 4B.

FIG. 5 is a flow chart for explaining a music file reproducing processof a mobile communication terminal according to an exemplary embodimentof the present invention.

Hereinafter, FIG. 5 will be explained with reference to FIGS. 1 and 2.

The control unit 160 converts the signal receiving sound output mode tothe manner mode on the basis of a request from a user and performs thecorresponding operation at step S210.

The control unit 160 examines whether the reproduction of the musicfiles, for example, MP3 files, is requested by the user during themanner mode of the mobile communication terminal 100 at step S220.

If the reproduction of the music files is requested by the user, afterstarting the music file reproduction mode, for example, MP3 reproductionmode, of the mobile communication terminal 100, the control unit 160outputs the confirmation message for determining whether the music filesare to be reproduced or not when performing the manner mode at stepS230. The confirmation message informs the user that the mobilecommunication terminal 100 is performing the manner mode when thereproduction of the music files is requested by the user, and enablesthe user to confirm whether the music files are to be reproduced or notduring the manner mode of the mobile communication terminal 100. Theconfirmation message is output in a voice message through the audioprocessing unit 130 or in a letter message through the display unit 190.

If a predetermined key, for example, confirmation key, is input at stepS240, the control unit 160 determines that the user confirmed the outputconfirmation message at step S250. It is preferable that thepredetermined key is the confirmation key provided in the key input unit140. Further, the predetermined key can be a key provided or embodiedfor the reproduction of the music files.

If the confirmation message is determined to be confirmed by the user,the control unit 160 reproduces the music files selected by the user atstep S260. The audio signals of the reproduced music files are outputthrough the speaker of the audio processing unit 130.

On the other hand, in the case where incoming call signals are receivedduring the reproduction of the music files, it is preferable that thecontrol unit 160 stops the reproduction of the music files and outputsan indication of the reception of the incoming call signal without soundor by vibration according to the set manner mode.

FIGS. 6A and 6B are exemplary views for explaining the operation of themobile communication terminal according to an exemplary embodiment ofthe present invention.

FIG. 6A shows a screen outputting the confirmation message fordetermining whether the music files are to be reproduced or not inresponse to the reproduction request of the music files during themanner mode of the mobile communication terminal 100.

If a user inputs a key or a confirmation key for the reproduction of themusic files in the state of FIG. 6A, the mobile communication terminaldetermines that the user confirmed the confirmation message or that themusic files can be reproduced, and reproduces the music files selectedby the user together with the music file reproduction screen as shown inFIG. 6B.
